+## 2026-02-07 - 1.17.1 - fix(registrycopy)
+add fetchWithRetry wrapper to apply timeouts, retries with exponential backoff, and token cache handling; use it for registry HTTP requests
+
+- Introduces fetchWithRetry(url, options, timeoutMs, maxRetries) to wrap fetch with AbortSignal timeout, exponential backoff retries, and retry behavior only for network errors and 5xx responses
+- Replaces direct fetch calls for registry /v2 checks, token requests, and blob uploads with fetchWithRetry (30s for auth/token checks, 300s for blob operations)
+- Clears token cache entry when a 401 response is received so the next attempt re-authenticates
+- Adds logging on retry attempts and backoff delays to improve robustness and observability
+
 ## 2026-02-07 - 1.17.0 - feat(tsdocker)
 add Dockerfile filtering, optional skip-build flow, and fallback Docker config credential loading
